COTTON-BALE TIE.

SPECIFICATION forming part of Letters Patent No. 225,51*?, dated March16, 1880.A

Application flied october 10,1879. 4

To all whom it may concern:

Beit known that I, SAMUEL H. GILMAN, of New Orleans, in the parish ofOrleans and State of Louisiana, have invented a new and usei'ulImprovement in CottonBale Ties; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings,

forming part of this specification, in which- Figure l is a top end Viewof the improved tie., Fig. 2 isanbottomjend view of the same. Fig. 3 isa vertical longitudinal section of the tie, the griping globes or ballsbeing in their inactive position.' Fig. 4L is a vertical transversesection of the same, the globes or balls being partially in their activeposition; and Fig. 5 is a section similar to Fig. 4, the balls being infull action and occupying their eX- treme lower position. Fig. 6 is adiagram for 2o illustrating, in connection with the descriptionhereinafter given, the operation of the tie.

My invention relates to the globe or ball tie for bale-bands patented byme June 18, 1878, No. 204,965 5 and the object of the improvement whichI have now made is to provide against the slipping of the end of theband after the tie has been applied toit; also, to insure a bite of theglobes or balls upon the band from the time they first touch the banduntilv and 3o during the greatest strain upon the band.

In operating with the various descriptions of ties for cotton-balesduring several years, I have discovered that the angle formed by theband with respect to the bearing-surface 3 5 for the` balls, and uponwhich the balls or globes should be applied to bite or gripe upon theband, cannot with any practical utility be less than six degrees normorelthan ten degrees, and that the most successful angle upon 4o whichthe balls should be applied so as to gripe or bite upon the band withunerring certainty at all times is about seven and a half degrees.

The nature of my presentinvention consists in certain details ofconstruction ot' the tie heretofore patented by me, whereby the balls orglobes used for biting or griping upon the band are presented to theband on an angle ranging from six degrees to ten degrees, pret- 5oerably at an angle of seven and a half degrees,

and whereby the band is prevented from being deiected by the firstcontact of the balls therewith in such manner as to form an anglegreater than ten or less than six degrees.

ln the accompanying drawings, A represents a metal tie of attenedtubular form and tapering lengthwise. The tie is about one inch inlength, and through it a broad oblong passage, a, is formed, saidpassage being equal in width to the cotton-bale band b b', which is 6oto be passed through it, as shown. Both faces of the metal forming the.broad sides of the l passage a are corrugated or channeled,l as shownat c and d, the channels cpbeing much deeper than those d, and areformed by ribs e e, which, in cross-section, are of wedge shape. Theseribs are of nearly uniform depth from end to end of the tie, and betweenthese ribs are semicircular channels or grooves o, corresponding inform, in transverse section, to the 7o surface of the balls B, whichroll and travel in them during the operation of tying the bands upon thebale. The channels l are very shallow, and are formed upon the surface gof the tie, against which the end b of the band bears, and they areopposite the semicircular chau- .nels c, and permit the band to bedepressed slightly within the tie when the strain of the band is actingupon the balls.

At the upper end of the tie, and on Vside g 8o where the deeper channelsare formed, a guard lip or rib, f, is provided for the purpose ofpreventing the balls passing out of the tie at its upper end. The inneredge, f', of this rib f is on about the same vertical plane with the 8 5lower terminus, e', of the ribs c.

The downward-extended inner bearing-surface, g, is inclined to a veryconsiderable extent, while the other, g', is less inclined, and thesesurfaces, together with their guard f 9o and ribs e, are so arrangedrelatively to each other that an angle of about seven and a half degreesis formed for the bite ot' the balls between the outer surface, s, ofthe band d, Vthe ribs e, and the lower terminus, e', of the 95 ribs e,and consequently the balls or globes B bite the band on that angle latthe first impingement of the balls upon the band, and continue to bite(on a slightly-decreasing an gle) upon the band from the said firstimroo pingement (shown in Fig. 4:) till the balls are fully seated, assignified in Fig. 5.

There of course Will be a slight change in the extent of the angle uponWhichthe balls bite or gripe, due to the compression of the 'metal ofthe bands and the depression of the sameinto the shallow corrugations d;but this is so slight that it Will not materially chan ge the angle orcause the balls to jam and Wedge so tight that the tie cannot be readilyunlocked.

It Will be seen from the diagram shown in Fig. 6 that an inclination ofseven and aA halfI degrees (represented by the lines g and s) causes thepoint of impingement t and u to stand very near the diameter D oftheball B, and thus a quick and sure bite between the two inclined sides issecured.

It Will also be seen that with a slight increase of the angle of thelines g s the points of impingement will be caused to stand so reA motefrom the diameter D of the ball-as, for example, the points t @LL-as torender a biting impingement almost impossible with the same ball.

By providing for the biting of the balls upon an angle of from six toten degrees, the ties can be made much shorter and the balls smaller,and, as two or more balls are employed in each tie, the bite Will bedistributed over a cotton-bale band of ordinary commercial Width', andits hold will be much more effective and less destructive to the bandthan that of a single large ball and larger tie.

In some cases it may be desirable to adopt au angle of six degrees, oran angle ranging from six to ten'degrees; but my experience proves thatseven and a half degrees is the most sure and proper one to adopt. I donot, therefore, limit myself to an angle of seven and a half degrees,but desire to employ an angle ranging from six to ten degrees.

/Vhat I claim isl. The'cotton-bale tie having its ribs e at their lowertermini, e', of a depth about equal to the depth of the guard-ribf, andits broad sides g g, against which the band and balls bear,respectively, constructed and arranged in relation to one anothersubstantially as and for the purpose set forth.

2. The cotton-bale tie provided with surfaces g g', guard-ribf, and ribse, arranged to form an angle for the balls B to bite or gripe upon, ofnot less than six nor more than ten degrees, preferably seven and a halfdegrees, between the band and the ribs c, substantially as and for thepurpose set forth.

Witness my hand in the matter of my application for a patent on acotton-bale tie this 6th day of October, A. D. 1879.
